Overview

Pattern matchers for detecting optimization opportunities in Ruby AST.

Each pattern class inherits from Base and implements visit_* methods to detect specific anti-patterns using Prism's visitor interface.

Examples:

Creating a custom pattern

class MyPattern < Base
  self.pattern_id = :my_pattern
  self.optimization_type = :cpu

  def visit_call_node(node)
    super
    # detection logic here
  end
end
